Which of the following is a conditional statement? Question 15 options: A) The quadrilateral has a set of parallel sides and is a trapezoid. B) A polygon is a pentagon if it has five sides. C) The polygon has six sides, but it isn't a regular hexagon. D) The shape is a triangle, and it has an obtuse angle.

The correct option is B

B) A polygon is a pentagon if it has five sides

Step-by-step explanation:

Conditional statement is a statement which relate the hypothesis and the conclusion. A simple way to identify a conditional statement is to look out for the words if, if-then, if-else which usually occur in all conditional statements.

In the given option B, the hypothesis is that "If it(polygon) has five side" and the conclusion is that "A polygon is a pentagon"

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
